Stellest vs Miyosmart For Myopia Control
Understanding Myopia Control in Children
Myopia, or nearsightedness, happens when the eyeball grows too long from front to back. The more it grows, the higher the prescription becomes. High myopia in adulthood raises the risk of serious conditions like retinal detachment, glaucoma, cataracts, and myopic maculopathy (myopic macular degeneration).
Slowing this growth during childhood can keep your child's final prescription lower and may reduce those long-term risks. Even a modest reduction in progression can make a meaningful difference over a lifetime. Slowing progression is probabilistic and does not guarantee prevention of future complications, but it can lower the likelihood.
Myopia control lenses work best for children whose myopia is progressing year after year. We typically recommend them for kids between ages six and early teens, when the eyes are still growing rapidly.
- Children whose prescription has increased by 0.50 diopters or more in one year
- Kids with a family history of high myopia
- Children who spend long hours on close work or limited time outdoors
- Any child whose parents want to slow progression and reduce future risks
Rapid myopia progression often shows up in subtle ways. Your child might start squinting more at the board in school or complain that their glasses do not seem as clear as they used to be. You may notice they sit closer to the TV or hold books very near their face.
If your child needs a new prescription every six to twelve months, that signals faster-than-average progression. Tracking these changes helps us decide when to introduce myopia control treatment.
Standard single-vision glasses correct blurry distance vision but do not slow down how fast myopia worsens. Your child will see clearly, but the eyeball may continue to grow at the same pace, leading to stronger prescriptions over time.
Myopia control lenses look similar to regular glasses and provide clear distance vision, though some children notice mild peripheral blur or visual artifacts during the adaptation period. The key difference is the special design built into the lens that creates focused and defocused zones. This sends signals to the eye that can slow down excessive growth.
Beyond specialized lenses, daily habits and environmental factors play a role in managing myopia progression. While no lifestyle change alone can replace myopia control treatment, combining these strategies with your child's lenses may provide additional benefit.
- Encourage at least two hours of outdoor time each day when feasible
- Take regular breaks during close work using the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds
- Maintain good lighting and a proper working distance for reading and screen time
- Ensure consistent sleep and daily routines that support overall eye health
- Schedule regular comprehensive eye exams to track changes early
What Are Stellest and Miyosmart Lenses?
Stellest lenses feature a ring of tiny aspherical lenslets arranged around the central viewing zone. These lenslets create myopic defocus signals that are positioned in front of the retina, which research suggests slows eyeball elongation. The center of the lens provides clear vision, while the surrounding treatment zone works constantly as your child looks through different parts of the lens.
This design is called H.A.L.T., which stands for Highly Aspherical Lenslet Target. The lenslets are invisible to others but do create a slight appearance difference when your child looks closely at the lens itself.
Miyosmart lenses use hundreds of small segments distributed across the lens in what is called DIMS technology. These segments create myopic defocus, meaning certain zones of the lens focus light slightly in front of the retina instead of directly on it. This defocus signal is thought to tell the eye to slow its lengthening.
The central zone gives clear, sharp vision for everyday tasks. The surrounding honeycomb pattern of segments provides treatment all day as your child wears the glasses.
Both DIMS and H.A.L.T. rely on the same principle: imposing myopic defocus in the periphery or across treatment zones of the lens. These designs aim to create myopic defocus while preserving a central distance-correction zone; the exact optical profile and distribution differ by brand. Animal and human studies suggest that this type of defocus slows the biochemical signals that drive eyeball growth. Clinical trials for both technologies have shown meaningful reductions in axial length increase, the measurement that corresponds to myopia progression.
While the designs differ in the exact shape, size, and arrangement of the treatment zones, they share the goal of shifting where light focuses to slow down progression. Both have published peer-reviewed data supporting their effectiveness as of 2025.
Unlike orthokeratology, which uses overnight contact lenses to reshape the cornea, Stellest and Miyosmart are regular eyeglasses your child puts on in the morning and wears throughout the day. There is no need to handle contact lenses, no overnight wear, and no special solutions or storage cases.
- Safe for children who are not ready for contact lens responsibility
- Avoids contact-lens-related infection risk (no overnight lens wear or lens handling)
- Eye irritation, allergies, or unrelated infections remain possible as with any eyewear
- Easy to clean with standard lens cleaner and a microfiber cloth
- Can be paired with anti-reflective and scratch-resistant coatings
Comparing Stellest and Miyosmart Effectiveness and Features
Published clinical trials have reported that both Miyosmart and Stellest may reduce myopia progression on average, but results are not directly comparable across separate studies because trial designs, populations, endpoints, and control groups differ. Miyosmart studies have reported reductions in progression ranging from roughly 50 to 60 percent depending on whether refractive change (diopters per year) or axial elongation (millimeters) is the primary endpoint. Stellest studies have reported similar ranges, with some endpoints showing reductions around 60 to 67 percent on average over two years in children who wore the lenses at least twelve hours daily.
Percent reductions vary by baseline age, starting prescription, adherence, and how progression is measured. Individual children respond differently. Some may see greater benefit, while others may progress despite treatment. Regular monitoring helps us track your child's specific response.
Miyosmart is commonly available for children ages six to eighteen, with myopia up to around negative 10.00 diopters and astigmatism up to negative 4.00 diopters, though specific ranges can vary by manufacturer updates and region. Stellest is similarly available for comparable age groups and generally accommodates prescriptions up to about negative 10.00 diopters of myopia with moderate astigmatism. Availability varies by country, lab, and current product parameters; we verify ranges at ordering.
Our eye doctor will confirm whether your child's current prescription falls within the available range for each lens. Higher levels of astigmatism or significant differences between the two eyes may limit suitability or require individualized planning. If your child's prescription is at the edge of these limits, we may discuss whether one lens offers more flexibility than the other.
From a distance, both Stellest and Miyosmart look like standard eyeglasses. Up close, the treatment zones create a subtle texture or pattern on the lens surface. Miyosmart has a honeycomb appearance if you examine it closely, while Stellest shows concentric rings of tiny lenslets.
Most children do not notice these patterns during normal wear. Other people rarely spot the difference unless they look directly at the lenses. Many kids feel confident and comfortable wearing either design at school and during activities.
Both lens types are commonly available in impact-resistant materials suitable for active children. They can be fitted with anti-reflective coatings to reduce glare and scratch-resistant coatings to help them last longer. We recommend a sturdy frame that fits well and stays in place during play and sports.
- Polycarbonate or similar materials for impact resistance
- Compatible with UV protection coatings
- Designed to withstand typical childhood activities
- No special storage required beyond a protective case when not worn
Myopia control lenses generally cost more than standard single-vision lenses because of the specialized design and manufacturing. Prices can range from several hundred to over a thousand dollars for the lenses alone, depending on the brand, prescription complexity, and additional coatings. Frames, fitting fees, and follow-up visits add to the total investment.
The exact cost varies by practice and region. We will provide a detailed estimate during your consultation so you can plan accordingly and check whether your vision insurance offers any coverage for myopia management.
Getting Evaluated and Fitted for Myopia Control Lenses
Before prescribing myopia control lenses, we perform a comprehensive eye exam to confirm your child's current prescription and overall eye health. This typically includes cycloplegic refraction, which uses dilating drops to relax the focusing muscles and obtain the most accurate measurement of your child's true prescription. We also review your child's myopia history by looking at how much the prescription has changed over the past one to two years.
Additional tests may include checking the front surface of the eye, examining the retina, and assessing how the eyes work together. We evaluate binocular vision and accommodation to ensure your child can adapt comfortably to the lens design and to help troubleshoot any symptoms like headaches or eye strain. These tests help rule out other conditions that could affect treatment success.
We typically use an optical biometer to measure axial length, the distance from the front to the back of the eyeball. Optical biometry is the standard for routine myopia management, though ultrasound A-scan is an alternative method in some settings. This measurement is the most accurate way to track myopia progression, because the eyeball grows longer as myopia worsens.
Baseline axial length readings give us a starting point. Follow-up measurements every six months let us see whether the lenses are slowing growth as expected. Even small decreases in the rate of elongation can add up to meaningful benefits over several years.
The decision between Stellest and Miyosmart depends on your child's prescription, age, lifestyle, and personal preferences. If one lens is not available in your child's exact prescription or astigmatism level, that may narrow the choice. Some families prefer the specific study data for one design over the other.
- Prescription range and cylinder limits
- Availability and ordering timelines in our practice
- Your child's comfort and willingness to wear glasses full time
- Cost differences and insurance considerations
- Our clinical experience with each lens type
During the fitting visit, we measure the distance between your child's pupils, the fitting height, and other frame parameters to ensure the lenses are centered correctly. Proper alignment is essential because the treatment zones must sit in the right position relative to the pupil. We also adjust the frame so it sits comfortably on your child's nose and ears without sliding.
The appointment typically takes about thirty to sixty minutes. Once measurements are complete, we order the custom lenses, which usually arrive within one to three weeks. When the glasses are ready, we schedule a dispensing visit to check fit and vision before your child starts wearing them full time.
Living with Stellest or Miyosmart Lenses
Most children adapt to myopia control lenses within a few days to two weeks. Some notice slight differences in peripheral vision or minor distortions at the edges of the lens during the first week. These sensations usually fade as the brain adjusts to the new lens design.
Encourage your child to wear the glasses consistently from the start. The more they wear them, the faster they will adapt. If discomfort or visual disturbances persist beyond two weeks, contact our office so we can check the fit and prescription.
Clinical studies show the greatest benefit when children wear myopia control lenses at least ten to twelve hours every day. Consistent wear throughout waking hours ensures the treatment zones are working as designed. Taking the glasses off frequently or wearing them only part time reduces their effectiveness.
- Put glasses on in the morning and keep them on until bedtime
- Wear them during school, homework, and outdoor play
- Use a sport strap or secure frame for active children
- Set reminders or routines to build the habit
Clean the lenses every morning or whenever they get smudged. Use a gentle lens cleaner or warm water with a drop of dish soap, then dry with a clean microfiber cloth. Avoid paper towels or clothing, which can scratch the lens surface and damage the treatment zones.
Store the glasses in a hard protective case when not being worn. Teach your child to handle the frames by the temples, not the lenses, to prevent fingerprints and scratches. Regular care keeps the optics clear and extends the life of the lenses.
We typically schedule follow-up appointments every six months while actively treating and monitoring progression. The interval may be individualized based on your child's age, rate of progression, and treatment response, and many children continue six-month visits even when stable to ensure ongoing axial length trending and prescription accuracy. At each visit, we measure axial length, update the prescription if needed, and confirm the lenses still fit properly. We also ask about wearing habits, comfort, and any vision changes.
These visits let us track how much the treatment is slowing progression. If the rate of growth remains too high, we may discuss adding another intervention, such as low-dose atropine drops, or switching to a different myopia control strategy.
Some symptoms require same-day urgent evaluation, even if unrelated to the myopia control lenses themselves, because they may signal serious eye conditions. Other concerns should prompt you to call our office soon for assessment and guidance.
Seek same-day urgent evaluation for:
- Sudden vision loss or a curtain or shadow in your child's vision
- Flashes of light or a sudden increase in floaters
- Significant eye pain or trauma
Call our office soon if your child experiences:
- Persistent headaches or eye strain beyond the two-week adaptation period
- Blurry vision that does not clear with the glasses after the initial adjustment
- Redness, discharge, or irritation that does not resolve quickly
- Damage to the lenses or frame that affects fit or vision
Frequently Asked Questions
Yes, switching between Stellest and Miyosmart is possible if the first choice does not fit well, causes discomfort, or does not slow progression as hoped. We will re-measure and fit your child for the new lens design. Keep in mind that switching may involve additional cost and a brief re-adaptation period.
If follow-up axial length measurements show your child's eyes are still growing quickly despite good compliance, we may recommend combining the lenses with low-dose atropine eye drops or considering a different approach like orthokeratology. No single treatment works perfectly for every child. We monitor closely and adjust the plan as needed to give your child the best chance of slowing progression.
Orthokeratology uses overnight contact lenses to reshape the cornea and also slows progression, but it requires nightly lens insertion and carries a small risk of corneal infection. Low-dose atropine drops are applied once daily at bedtime and can slow myopia, but may cause light sensitivity or near blur in some children. Myopia control glasses like Stellest and Miyosmart require no nightly routine, no eye drops, and no contact lens care, making them a simpler option for many families. Some practitioners combine glasses with atropine for greater effect.
Most children benefit from myopia control treatment until their eyes stop growing, usually in the mid to late teen years. The exact duration depends on when treatment starts and how long your child's myopia continues to progress. We review growth patterns at each visit and will discuss tapering or stopping treatment when progression has stabilized for at least one year.
These lenses are designed and studied primarily for children whose eyes are still growing. Teens in their mid to late adolescence may still benefit if their myopia is progressing, but effectiveness tends to decrease as growth slows. Adults whose eyes have stopped growing generally do not see progression, so myopia control lenses are not typically necessary or recommended for them.
Coverage varies widely by insurance plan. Some vision plans offer partial reimbursement for myopia management as a medical benefit, while others do not cover specialty lenses at all. We recommend contacting your insurance carrier before the fitting appointment to ask about benefits for myopia control treatments. Our staff can provide documentation and codes to help you file a claim if coverage is available.
